We’ve worked with…

I have used Thornhill Decorators on a number of occasions. Everytime they have been professional, tidy and completed the work to a very high standard with no fuss. I would and probably will use them again.

Mr D. Peterson

We have recommended you to everyone we know, fabulous job, great communication. No complaints whatsoever!

Mr & Mrs PM Bird

Very good service, you exceeded my expectations, I would recommend you and would use you again.

Dr H. Young

I found the Decorators to be extremely clean and tidy in their appearance and the way they cleaned up at the end of each day.
